Method and a system for providing a driving-range forecast for a vehicle

A system for providing a forecast of a driving-range of a vehicle, the system comprising:

• a power-source configured to propel the vehicle;
• an energy storage device configured to supply energy to the power-source;
• and
• a controller configured for:
• determining a state of charge (SOC) of the energy storage device;
• accessing geographical and road map data from a remote source;
• calculating a historical average distance traveled by the vehicle per the determined SOC;
• determining an available driving-range according to the geographical and road map data and the determined historical average distance traveled;
• establishing a rate of charge of the energy storage device;
• determining one of an increase in the SOC to be achieved during a predetermined period of time and an additional period of time needed to generate a predetermined increase in the SOC;
• and
• determining an incremental change in the available driving-range according to the geographical and road map data and the historical average distance traveled per one of the determined increase in the SOC and the predetermined increase in the SOC.
